Let's discuss the westbbound signal for track 2 at CP Kiski. The file SignalLogicKiskiWest2.png shows what I believe SSL is capable of. Apparently it can only specify a single turnout for the signal to react to. In my case, that signal needs to be red when turnout 303 is thrown (as shown on SignalLogicKiskiWest2.png), and also when turnout 304 is thrown (not on SignalLogicKiskiWest2.pnglosed) if turnout 303 is closed. Can this be accomplished using this tool? Or do I need to move to something more sophisticated?
You can do this, but it involves extra non-displaying SignalHeads. Roughly:
1) Define an internal / virtual head that is on the entrance to the furthest turnout. It¡¯ll show red if that¡¯s set against. (This isn¡¯t on the layout, though you might want to add it to a panel so you can see what¡¯s going on)
2) Now set up the real signal to (a) protect against the near turnout and (b) follow your signal from (1) as ¡°Distant¡±. That last part is important: ¡°Distant¡± means to be red when the far signal is red, not yellow when the far signal is red.
It can become complicated, but this should always be able to handle what needs to be handled.
